WebThe simplest definition of the 2nd. moment of area is I= A k2 Whilst standard formulae exist for calculating the radius of gyration of various simple shapes, we should examine the derivations from first principles. We do this by considering the area to be made up of lots of elementary strips of width b and height dy. The second moment of area, or second area moment, or quadratic moment of area and also known as the area moment of inertia, is a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis. The second moment of area is typically denoted with either an (for an axis that lies in the plane of the area) or with a (for an axis perpendicular to the plane). In both cases, it is calculated with a multiple integral over the object i… pajaro valley historical society
